Description
The Alumina Double and Four Bore Tube 99.5% is manufactured from 99.5% high-purity alumina (Al₂O₃), offering exceptional thermal stability, superior electrical insulation, outstanding mechanical strength, and excellent chemical resistance. Designed with double-bore and four-bore configurations, these ceramic tubes are widely used for thermocouple protection, electrical insulation, heating elements, and high-temperature laboratory and industrial applications.
With excellent resistance to thermal shock, oxidation, corrosion, and wear, these alumina tubes ensure reliable performance under extreme operating conditions. Their precision-engineered multi-bore design allows safe routing of thermocouple wires and electrical conductors while maintaining excellent insulation and long service life.
